The Energy of a Cosmic Ray Is Given By γ\gamma Mc2, Where M Is the Mass of the Particle, C

Question 62

Essay

The energy of a cosmic ray is given by γ\gamma mc2, where m is the mass of the particle, c is the speed of light, and γ\gamma is the Lorentz factor and The energy of a cosmic ray is given by \gamma mc<sup>2</sup>, where m is the mass of the particle, c is the speed of light, and \gamma is the Lorentz factor and . If a cosmic ray proton is traveling at a speed of \nu = 0.999999c, what is its energy? How does that compare to the kinetic energy of a grape thrown up in the air and caught in your mouth? Assume the grape has a mass of about 5 grams and a speed of 0.5 m/s when you catch it. The mass of a proton is 1.7 * 10<sup>-27</sup> kg. . If a cosmic ray proton is traveling at a speed of ν\nu = 0.999999c, what is its energy? How does that compare to the kinetic energy of a grape thrown up in the air and caught in your mouth? Assume the grape has a mass of about 5 grams and a speed of 0.5 m/s when you catch it. The mass of a proton is 1.7 * 10-27 kg.
